CHAMBERSBURG >> Mistaken identity may be the cause behind the January 2014 fatal shooting of Timothy "Asti" Davison Jr., investigators announced Monday.

John Wayne Strawser Jr., 38, is charged with first degree murder in the shooting of Davison, 28, but investigators believe Strawser had another target the night of the incident.

Davison was driving from Florida, where he was visiting his sister, to his home in Maine around 2:10 a.m. Jan. 4, 2014, north on Interstate 81, when police said he was approached by Strawser's dark colored Ford Ranger. Davison called 911 and said someone in the pickup was firing gunshots at his vehicle, continuing for a few miles as he approached Pennsylvania from Maryland.

Around exit 3 in Antrim Township, Davison told the dispatcher that the pickup truck forced him into the median, then continued driving north. While on the phone, Davison exclaimed that the driver, now identified as Strawser, was back at the scene.

Police said that in a recording of the 911 call an engine revving is audible, along with shots being fired and the squeal of wheels accelerating away from the scene.

Investigators have determined that is when Davison was shot in the hand, right leg and head.

Davison was transported to York Hospital for treatment, where he died from his injuries.

Identifying the suspect

Fast forward to April 20, 2015 and thousands of tips later, local man Jamie Breese comes to Pennsylvania State Police saying he believed Strawser may be involved.

Breese's wife Courtney Breese had an affair with Strawser, she told investigators, and said the family friend was unpredictable and had been possessive and violent around the time of Davison's shooting. This included Strawser making threats and showing up at places near their home, despite him living two and a half hours away in Terra Alta, West Virginia.

Breese told police that he saw the news of Davison's shooting the day after it happened and wondered if Strawser did it, but his wife dismissed the idea. Breese said other people told him that Strawser would kill him to get to his wife.

The night of the incident, the Breeses were at a club in Bunker Hill, West Virginia when Strawser began calling and texting them, wanting to know where they were. They told him they were at the club, and a short time later saw him come out of the bathroom there.

However, they decided to avoid him because they had a falling out with him prior to seeing him that night, and hadn't spoken to him directly in months, according to police.

Strawser was also threatening them that night, investigators said. There was a "volatile" relationship and the couple left going north on Interstate 81, into Pennsylvania.

It was when Breese saw that Strawser was charged in the homicide of Amy Lou Buckingham in Kingwood, West Virginia, on April 15, 2015, that he decided to come forward.

During a press conference at the PSP Troop H Headquarters in Harrisburg Monday afternoon, Lt. Jonathan Mays said there were definite similarities between Davison's murder and the homicide of Buckingham. Mays said it was his understanding that there was a romantic involvement in the Buckingham murder also, and that Strawser had multiple relationships with many women.

Asked by reporters if Strawser might have committed other crimes in other areas, Mays said investigators are now looking at similarities in other crimes. He did not elaborate on what those might be.

Breese determined that Strawser had actually been hunting him and his wife that night, not Davison, and mixed up their silver Honda Pilot for Davison's silver Mitsubishi Montero.

Since April 15, police ran a variety of tests on both items and found Strawser's gun matched the gun used in the shooting and that his DNA matched a sample found on a shell casing at the scene. They also found evidence of gunshot residue on the driver's side of Strawser's pickup.

Finally, in Strawser's phone records, they found that he was on the phone in his vehicle driving from Martinsburg, West Virginia to Hagerstown, Maryland, ending the call at 1:56 a.m. Davison's first call to police was at 1:59, when he was in Hagerstown.

A check with Strawser's employers also told investigators that he had not been working that night, as he originally told them.

When police asked Strawser if something happened on I-81 that led to the death of Davison, Strawser replied "I don't remember," according to court documents.

A job well done

Franklin County District Attorney Matt Fogal said during a press conference in Chambersburg Monday afternoon that he was very thankful for the patience of Davison's family in the investigation.

He also thanked state police troopers, specifically Troopers Jason Cachara and David Rush.

"Thank goodness he's off the street. He was on the street for over a year after this particular murder occurred," Fogal said. "I hope the community feels very safe and very happy with the work that PSP has done in this case."

Davison's mom, Theresa Allocca, said that her family is pleased and relieved that authorities have Strawser.

"It's really unfortunate those people didn't come forward when they should have," Allocca said. "It just doesn't feel right. I feel really sad for (Buckingham's) family," she added, referring to the other murder case against Strawser.

Allocca said she is happy that the Franklin County area can rest a little easier tonight. "I know many of them have been so supportive for us, sharing our Facebook page, sending personal messages," Allocca said. "Just a real outpouring from their community, people pulling together."

Allocca, who has said previously that she forgives the person that shot her son, said she continues to be in a place of forgiveness and faith after Strawser's arrest.

"It's just not my place to judge him. I don't know what his life is like," Allocca said. "Do I think he's made really bad choices? I don't know if people like that can get rehab, but i just kind of let it go. I don't want hatred to ruin my life."

Strawser is in custody at the Tygart Valley Region Jail in Belington, West Virginia, where he is being held as a pre-trial felon. Strawser has been in custody since April 17.
